honestly, i've found that it's usually better to not engage in these threads. the likelihood of a good faith discussion is very low. as you point out, it's mostly ideological kneejerk reactions rather than actual discussion based on considered viewpoints. but i'll give it a go.

i personally don't like this for a few reasons. possibility of data leaks, ick factor via my built-in paranoia around being watched/recorded, possibility of false positives etc. but i have some faith in TfL / BTP to not piss about in an egregious way. we have pretty decent checks and balances these days for UK police compared to the past and definitely compared to some police forces in the states. i'm also aware that as a man i tend to not experience the same shit that a lot of women have to deal with on a daily basis.

so i might be willing to accept it as part of a necessary trade-off based on my real life experiences on the tube. i'd probably be willing to accept having my face recorded/pattern matched when using the tube if it either stops or helps to prosecute a sexual assault.

there is definitely a difference between liking something and accepting it.
